Hey everyone! Betsey Stevenson here from President Obama’s Council of Economic Advisers. In honor of Women’s Equality Day, I’ll be taking over I Love Charts to tell the story of the progress we’ve made in closing the earnings gap between women and men, and the challenges women still face in the workforce.
Betsey says it better than we can. Have a look at the results.
Also, hey, Happy Women’s Equality Day, Tumblr.
I shot an arrow into the air,
It fell to earth, I knew not where;
For, so swiftly it flew, the sight
Could not follow it in its flight.
I breathed a song into the air,
It fell to earth, I knew not where;
For who has sight so keen and strong,
That it can follow the flight of song?
Long, long afterward, in an oak
I found the arrow, still unbroke;
And the song, from beginning to end,
I found again in the heart of a friend.

One of the first ever drawings of a fuel cell (1842)
Sir William Robert Grove, judge & physicist, was the father of the modern fuel cell. He developed his idea through experimenting with sending an electric current through water splitting it into its component parts of hydrogen and oxygen. He then tried to reverse the process and combine hydrogen with oxygen to produce electricity and water thereby producing a simple fuel cell.
In this letter from the Ri’s archive, Grove writes to Michael Faraday in October 1842 to describe his new accomplishment:
I have just completed a curious voltaic pile which I think you would like to see, it is composed of alternate tubes of oxygen and hydrogen through each of which passes platina foil so as to dip into separate vessels of water acidulated with sulphuric acid the liquid just touching the extremities of the foil as in the rough figure below…………………….
……………. I cannot but regard the experiment as an important one both as to the chemical and other theories of the pile & as to the catalytic effect of the combination of the gases by platina.
The modern fuel cell is used to power anything from cars, buses, boats and submarines to providing back up power to hospitals, houses and inaccessible areas.
'Street View' to Map Underwater Wonders
It’s easy to go online and get a 360-degree, ground-level view of almost any street in the U.S. and throughout the world. Soon, scientists hope people will be able to do the same with coral reefs and other underwater wonders.
U.S. government scientists are learning to use specialized fisheye lenses underwater in the Florida Keys this week in hopes of applying “street view” mapping to research and management plans in marine sanctuaries nationwide. Some of the rotating and panoramic images will be available online as early as this week, including a selection on Google Maps, giving the public a window into ecosystems still difficult and costly to explore for long stretches of time.

Music Rewires the Brain
Even old jokes can have a scientific basis in fact.
You know the one about the tourist who stops a native New Yorker on the street and asks, “Excuse me sir, but how do you get to Carnegie Hall?”
"Practice, practice, practice."
That New Yorker is absolutely correct. Scientists have found that the brains of professional musicians are physiologically different from the brains of other people, and they got that way mostly because of practice, practice, practice.

Christine de Pizan (1364- c. 1430)
Art by April Babcock (tumblr)
Christine de Pizan is one of the best known writers of the medieval period, yet if not for circumstances beyond her control she might never have picked up a pen. The daughter of an Italian scientist at the court of Charles V of France, Christine was given a classical education before her marriage at the age of fifteen to a royal secretary named Etienne du Castel. When she was 25, her beloved husband died in an epidemic. As her father had already passed away, Christine found herself responsible for the care of not only herself and her two children, but also her mother and an orphaned niece.
Christine began writing love ballads that caught the attention of wealthy patrons who enjoyed both her poetry and the novelty of a female writer. Christine wrote hundreds of poems, many on commission for specific nobles, and this work allowed her to support her family and clear the debts left after her husband’s death.
Christine’s most famous work, The Book of the City of Ladies (1405), is an impassioned defense of women. It challenged misogyny by creating a symbolic city of righteous women. The women profiled include historical figures such as Zenobia and Sappho, pagan goddesses such as Isis and Minerva, women from the Hebrew Bible such as Deborah and the unnamed Woman of Valor (Proverbs 31), and Christian saints such as the Virgin Mary and St. Lucy. Christine’s book was a testimony to the accomplishments of women and argued for wider access to education for women.
While The Book of the City of Ladies is primarily about female achievement, Christine also included an anti-rape message. As a character in the book, Christine says “I am therefore troubled and grieved when men argue that many women want to be raped and that it does not bother them at all to be raped by men even when they verbally protest…” Lady Rectitude, one of Christine’s guides in The Book of the City of Ladies, responds “Rest assured, dear friend, chaste ladies who live honestly take absolutely no pleasure in being raped. Indeed, rape is the greatest possible sorrow for them. Many upright women have demonstrated that this is true with their own credible examples…”
In 1418, Christine retired to a convent in Poissy. At the convent she wrote one final poem which she dedicated to Joan of Arc. It is the only known French language work about Joan of Arc written during Joan’s lifetime.
The International Mathematical Union has awarded the Fields Medal to four mathematicians—including, for the first time, a woman: Iranian Maryam Mirzakhani, a 37-year-old professor at Stanford.
Applause all around.
